request sample
Polyetherketone (PEK) is a high temperature semi crystalline thermoplastic that is a member of the polyaryletherketone (PAEK) family. It differs chemically by the respective number of cohesive ether and ketone groups that are present in the material's molecular structure. PEK is manufactured by Ensinger under the trade name TECAPEEK HT black, using VICTREX HT™ PEK polymer. PEK polymers offer higher wear resistance, as well as improved compressive strength at higher temperatures. A higher heat deflection temperature than standard PEEK allows for the mechanical properties and physical characteristics of TECAPEEK HT to be maintained at temperatures that are up to 30°C higher than standard PEEK.
